To give a bit of seed capital, wait to see what flies (and thus is very much de-risked) and then to force an additional round requiring dilution and board members that may simply be luggage to haul around should be up to the present day shareholders. The University is playing a dirty game here.
A friend of mine was in a similar situation, first round of funding was peanuts, second round - after substantial input in time, funds and efforts of the founders - on much less good terms (and effectively still peanuts) including board members and so on.
